Power Consumption Model of NDN-Based Multicore Software Router Based on Detailed Protocol Analysis

Abstract

NDN (Named Data Networking) has received considerable attention recently, mainly due to its built-in caching, which is expected to enable widespread and transparent operatorcontrolled caching. One of the important research challenges is to reduce the amount of power consumed by NDN networks as it has been shown that NDN's name prefix matching and caching are power-hungry. As a first step to achieving power-efficient NDN networks, in this paper, we develop a power consumption model of a multicore software NDN router. By applying this model to analyze how caching reduces power, we report that caching can reduce power consumption of an NDN network if the power consumption of routers is in proportion to their load and the computation of caching is as light as that of forwarding.

Load Balancing for Stateful Forwarding by Mitigating Heavy Hitters: A Case for Multi-Threaded NDN Software Routers

“…By precisely analyzing the loads of threads on realistic environments, we validate whether Interest packets with highly popular names are the root cause of load imbalance for NDN routers or not. The analysis here follows the model of the multi-threaded NDN router that we developed in our previous study [16]. The underlined number for each block in Fig.…”

A Cache Placement Strategy with Energy Consumption Optimization in Information-Centric Networking

“…In [27][28][29], the GreenICN concept has been proposed, and it aims to bridge this gap, addressing how the ICN network and devices can operate in a highly scalable and energy-efficient way. The team is very well positioned to design, prototype, and deploy GreenICN technology, and validate usability and performance of real-world GreenICN applications, contributing to creating a new, low-energy ICN.…”

“…In one study [25], the authors introduce the Network-oriented Information-centric Centrality for Efficiency (NICE) as a new metric for cache management in ICN. Reference [26] proposes an N-hop content store-based caching policy and routing protocol.In [27][28][29], the GreenICN concept has been proposed, and it aims to bridge this gap, addressing how the ICN network and devices can operate in a highly scalable and energy-efficient way. The team is very well positioned to design, prototype, and deploy GreenICN technology, and validate usability and performance of real-world GreenICN applications, contributing to creating a new, low-energy ICN.In general, we can see that the deficiencies in the above strategies mainly include: (1) The placement of cache nodes is not considered from the perspective of the user; (2) the problem of energy saving in the research of ICN cache placement needs to be further studied.…”

Bringing Information Centric Networking to Challenged Environments: An overview of the Second Workshop on Future Internet Architecture for Developing Regions

“…The consortium produced several solutions on this direction, some of which were presented or discussed during the FI4D workshop (13)(14)(15)(16). Intrinsically, these solutions perfectly fit ANDs, and were the spin during the FI4D workshop.…”
